I had mixed feelings starting this manga after reading some of the other reviews, but in the first half the main characters really grew on me. Yes, they are bizarre, weird, but there is an underlying charm to them nevertheless. I must say I really enjoyed the drawing of this manga.
As other reviews were quite negative about the end, just past the halfway mark I decided to see the last chapter. To say I was shocked is an understatement. I was also incredibly saddened by the whole thing. Now, even though I knew the end, I went back to where I had left off and finished it properly.
I'm glad I did, because there were several good bits of character development I would have missed out on, little bits of tenderness that make you actually like the characters even more, even though they are so totally perverted!

Reading the end again, I just wish it could have had a happier ending..... but as someone else said, not all stories have a happy ending.

Is it worth the read? If you enjoy fetishes and perverted acts, Yes; if you enjoy subtle char development, Yes; if you like this art style, definitely yes.... if you want a weird, perverted, fetish-filled story with a good ending, stay away.
